Alberta Bridge Inventory
In Alberta there are about 13,300 bridges.
Types of bridges in Alberta:
– Standard bridges 3521 (26%)
– Bridge size culverts 8348 (63%)
– Major bridges 1435 (11%)

Standard Bridges
Any bridge which is built according to standard drawings (plans) is classified as a standard bridge.
For inspection purposes standard bridges are divided into two basic features:
– Superstructure
– Substructure

Typical Bridge Components
Superstructure
– It carries the load applied to the deck and transfers it to bridge supports.
Substructure
– It transfers load from the superstructure to the foundation soil or rock.
– It includes all elements below the bearings.

Typical Bridge Components
Deck
‐ Provides a smooth & safe riding surface
– Transfers load of the deck to other components.
– Three common material used for the deck:– Wood
– Concrete
– Steel

Superstructure for Standard Bridges
Superstructure comprises of bearings and all elements above bearings, including:
– Bridgerail.
– Hazard markers.
– Timber stringers with timber deck.
– Reinforced concrete girders.
– Prestressed concrete girders.
– Bearings.

Standard Bridge & Culvert Components
• Reinforced Concrete Girders– Concrete is strong in compression and weak in tension.– Concrete bending members are reinforced with mild
reinforcing steel to produce reinforced concrete girders.
• Prestressed Concrete Girders– Girders are reinforced with high strength steel under tension. – Girders are designed not to crack.– Generally more economical.

Standard Bridge & Culvert Components
• Bearings– Neoprene or rubber pads or strips.
– Used over steel and concrete caps.
– Transmit all loads from superstructure to substructure.
– Permit longitudinal movement of the superstructure.
– Allow rotation caused by deflection.
